【産業上の利用分野】本発明は、実時間ビデオ信号の処理、特に、実時間ビデオ信号の遅延、レビュー及び連続性を管理することにより、ビデオ画像における時間を歪曲させる装置及び方法に関する。 BACKGROUND OF THE INVENTION The present invention, the processing of real time video signals, in particular, the delay of the real-time video signal, by managing the review and continuity, to an apparatus and method for distorting the time in the video image.

【0002】 [0002]

【従来の技術】実況ビデオ、放送ビデオ、一方向ケーブル・ビデオ及び有料ビデオにおいては、時間と直結したビデオ信号を発生している。 BACKGROUND OF THE INVENTION live video, broadcast video, in a one-way cable video and paid video is generating a video signal which is directly connected with the time. すなわち、番組は、ある時間に開始し、一定割合で所定期間放映される。 That is, the program starts at a certain time, for a predetermined period aired at a fixed rate. 多くの場合において、番組が開始すると、観察(視聴)者はビデオ信号源に対して制御できない。 In many cases, when a program is started, the observation (viewing) who can not be controlled with respect to the video signal source. このような場合のビデオを「実時間」ビデオと呼ぶ。 The video in such a case is referred to as a "real-time" video. この実時間ビデオを見ている際に、電話機やドアー・ベルに答えたり、家族の用事や、事務所内を歩行中の人に応答したりするために、 When you are looking at the real-time video, or answer the phone or door bell, family errands or, in order to and respond to the people while walking in the office,
視聴者が他に注意を向けると、その番組の情報や楽しみを逃してしまう。 When the viewer attention to the other, miss out on information and enjoyment of the program. このように情報や楽しみの機会を失うのを避ける1つの方法は、番組をビデオ・カセット・レコーダ(VCR)に録画して、後から見れるようにすることである。 In this way one way to avoid losing information and fun opportunities, and record programs on video cassette recorder (VCR), is to ensure that watch later. この方法では、ビデオ観賞の中断が生じた場合、番組が終了した後に、VCRを再生して、中断期間中に見損なった部分を見ることができる。 In this way, if the interruption of the video viewing occurs, after the program has ended, by reproducing the VCR, it can be seen portion Misokona' during the interruption period.

【0003】 [0003]

【発明が解決しようとする課題】しかし、上述のVCR The object of the invention is to be Solved However, the above-described VCR
を用いる方法では、ビデオ観賞の連続性がなくなり、その番組の情報や楽しみの価値が減少してしまう。 In the method using, there is no continuity of the video viewing, resulting in a decrease in information and value of enjoyment of the program. よって、このような中断にも関わらず、情報や楽しみの価値を失うことなく、これら情報や楽しみの価値を増加すると共に制御するために、時間的に線形又は非線形の方法で、番組を完全に観賞できるようにするビデオ番組の時間歪曲が望まれている。 Thus, despite such interruption, without losing valuable information and fun, to control with increasing value of these information and fun, temporally linear or non-linear manner, complete programs time distortion of video program that allows viewing is desired.

【0004】したがって、本発明の目的は、ビデオ番組を充分な期間だけ蓄積できる容量の再循環ランダム・アクセス・バッファに、この番組のビデオ内容を連続的に蓄積することにより、ビデオ観賞の時間を歪曲する装置及び方法の提供にある。 It is therefore an object of the present invention, the recirculation random access buffer capacity capable of storing video program only sufficient period, by continuously storing the video content of the program, the time of the video viewing to provide an apparatus and method for distortion.

【0005】 [0005]

【課題を解決するための手段】本発明によれば、番組のビデオ内容を圧縮して、所定時間内に蓄積できる番組の時間を延ばす。 According to the present invention SUMMARY OF], to compress the video content of the program, extending the time of the program that can be accumulated in a predetermined time. ビデオ観賞の中断が生じると、視聴者はバッファ(蓄積手段)内にマーカをつける。 When interruption of the video viewing occurs, the viewer put a marker in the buffer (storage means). そして、視聴者が戻ったときに、バッファからのビデオ再生をマーカ部分にて開始させるので、視聴者は、中断が生じた時点からのビデオ観賞を遅延状態で開始できる。 Then, when the viewer has returned, so to start the video playback from the buffer at the marker portion, the viewer may start a video viewing from the time of interruption has occurred in the delay state. 聴視者は、任意の所望速度でビデオを再生できるので、ある場面をスローモーションで観賞できるし、高速再生により実際のビデオに追いつくこともできる。 Acousto-optic person, it is possible to play the video at any desired speed, to be able to watch a scene in slow motion, it is also possible to catch up to the actual video by a high-speed playback. また、視聴者は、蓄積したビデオを再検討したり、ビデオの1つ以上の凍結フレームを観察することもできる。 Also, the viewer may or review the stored video, also possible to observe more than one freeze frame of the video. さらに、視聴者は、スタティク・バッファ内に蓄積するために実際のビデオの部分にマークを付け、任意時間の経過後に、その部分から再生をしたり、VCRに転送できる。 Moreover, the viewer, mark the actual portion of the video in order to accumulate Sutatiku-buffer, after a lapse of an arbitrary time, can be transferred playback from that part or, in VCR. バッファ内のビデオが圧縮されていれば、非圧縮形式で再生する。 If video in the buffer if it is compressed to play in uncompressed format. 視聴者が再生を行っている期間中も、バッファは新たな実時間ビデオを依然取り込んでいる。 During the period in which the viewer is performing the play also, the buffer have taken still a new real-time video.

【0006】本発明のその他の目的、利点及び新規な特徴は、添付図を参照した以下の説明より理解できよう。 [0006] Other objects of the present invention, advantages and novel features will be understood from the following description with reference to the accompanying drawings.
